Earth Resources Observation and Science (EROS) Center

The U.S. Geological Survey's (USGS) Earth Resources Observation and Science (EROS) Center in Sioux Falls, South Dakota, is a global leader in land imaging, using remotely sensed data to track how Earth is changing. EROS provides reliable, science-based information to help decision-makers understand how shifts in land use, cover, and condition affect people and the environment. This work is supported by one of the largest civilian archives of land imagery in the world—housing over 80 years of satellite and aerial data, including the full Landsat record. As the operational home of Landsat 8 and 9, EROS delivers daily observations that inform natural resource assessments, support national security, and help prepare for future challenges.

Resiliency of land change monitoring efforts to input data resampling Resiliency of land change monitoring efforts to input data resampling

The geometric transformation of remotely sensed imagery from one map projection to another necessitates a data resampling operation which alters the recorded values. The global Landsat archive is made available in the Universal Transverse Mercator (UTM) projection system which preserves geographic shape across small area but introduces small errors in distance and area. As remote sensing...

Validation of the geometric accuracy of airborne light detection and ranging data for eastern Iowa, 2019 Validation of the geometric accuracy of airborne light detection and ranging data for eastern Iowa, 2019

A geometric accuracy assessment of lidar data collected in eastern Iowa in 2019 as part of the 3D Elevation Program (3DEP) was conducted. The assessment involved evaluating interswath accuracy, same surface precision, point density, absolute accuracy, and consistency with adjacent 3DEP datasets. The results demonstrate that the data meet or exceed the quality level 2 specifications...

Assessing gap-filled Landsat land surface temperature time-series data using different observational datasets Assessing gap-filled Landsat land surface temperature time-series data using different observational datasets

Landsat Analysis Ready Data (ARD)-based time-series present challenges in monitoring surface urban heat islands (SUHI) due to rapid changes in land surface temperature (LST) compared to cloud-free satellite observations. This research investigates the use of a spatiotemporal gap-filling model as a feasible and cost-effective solution to produce Landsat time-series LST products with both...
